It complies with the modular transmitters basic requirements (Item 1 to 8) in FCC Part 15 Subpart C Section 15.212 as indicated below: Modular Approval Checklist: Modular approval requirement YesNo (1) Have its own RF shielding. (2) Have buffered modulation/data inputs. (3) Have its own power supply regulation. (4) Comply with the antenna and transmission system requirements of § 15.203, 15.204(b) and 15.204(c). (5) Tested in a stand-alone configuration. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in FCC § 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module. The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available. (6) Equipped with either a permanently affixed label or must be capable of electronically displaying its FCC ID. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. (7) Comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. (8) Comply with any applicable RF exposure requirements in its final configuration: The modular transmitter complies with FCC radiation exposure requirement. According to KDB447489D01(V05), SAR testing will be excluded if the test separation distance from the antenna and the outer surface of the device is greater than or equal to 8.2 9mm for the maximum tune-up tolerance (15.85mW [Average]). Please refer to RF Exposure sheet. Considering this point, the only host device which meets this requirement can be used. Masashi Tsuchida Mitsumi Electric Co Ltd

October 16, 2013 UL Japan, Inc. 4383-326 Asama-cho, Ise-shi, Mie 516-0021 Japan FCC ID: EW4W092 To whom it may concern, We, UL Japan, Inc, hereby declare that Wireless LAN module, model: W092 (FCC ID:EW4W092 ) of MITSUMI ELECTRIC CO., LTD is exempt from RF exposure SAR evaluation as its output power meets the exclusion limits stated in FCC Part 2 §2.1093. KDB 447498D01(V05) has the following exclusion for portable devices: The 1g and 10g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where •f(GHz) is the RF channel transmit frequency in GHz •Power and distance are rounded to the nearest mW and mm before calculation •The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. This device has f = 2.462 GHz and the maximum tune-up tolerance limit was 15.85mW. The minimum separation distance for this device can be calculated by the following formula. 15.85mW[maximum tune-up tolerance limit] / 3[1g SAR test exclusion threshold] * √2.462=8.29mm [minimum separation distance] If the minimum separation distance is more than 8.29mm, no SAR is required. Thank you for your attention to this matter. Masanori Nishiyama Manager of Head Office EMC Lab. WiSE Japan UL Verification Service UL Japan, Inc.
